[0064] The detailed description and technical content of this application will be explained below with reference to the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this application.
[0065] Figure 1 This is a perspective view of a front-opening substrate loading box with compatible operation according to the first embodiment of this application. (See also...) Figure 1 This application provides a front-opening substrate loading box with compatible operation, comprising a box body 100, a box door 200, a latch 300, a knob 400, and a handle 500. In this embodiment, the box body 100 has an opening 101, and the box body 100 in this embodiment is front-opening, that is, according to the predetermined usage configuration of the box body 100, the opening 101 is located on the front side of the box body 100. The box door 200 is located at the opening 101 and closes the opening 101.
[0066] Figure 2 This is an exploded perspective view of the door 200 of the front-opening substrate loading box, which is compatible with the first embodiment of this application. (See also...) Figure 1 and Figure 2In this embodiment, the door 200 is a flat, hollow rectangle. An operation window 201 is provided on the outer side of the door 200, and the operation window 201 communicates with the internal space of the door 200. Specifically, the door 200 includes a door base 210 and a panel 220. The panel 220 is disposed on the door base 210 and closes the internal space of the door base 210, and the operation window 201 is disposed on the panel 220.
[0067] See Figure 1 and Figure 2 A latch 300 is movably disposed within the door 200. In this embodiment, the latch 300 is disposed within the door seat 210 and can be longitudinally translated to extend from the side edge of the door 200 to latch the inner edge of the opening 101. In the simplest embodiment, a single latch 300 is sufficient to achieve the latching effect of the door 200 as intended in this application. In this embodiment, a pair of identical latches 300 are disposed on each of the two opposite sides of the door 200, i.e., four identical latches 300. In this embodiment, the four latches 300 are respectively disposed at the four corners of the door 200, thereby improving the reliability of the latch.
[0068] Figure 3 A front view of the door 200 of a front-opening substrate loading box compatible with the first embodiment of this application in the unlocked state. Figure 4 A cross-sectional view of the door 200 of a front-opening substrate loading box compatible with the first embodiment of this application in the unlocked state. (See also...) Figures 3 to 4 A knob 400 is pivotally mounted inside the door 200 and linked to the latch 300. In this embodiment, the knob 400 is pivotally mounted inside the door seat 210 and aligned with the operation window 201. The user can access the knob 400 through the operation window 201 to rotate it. The knob 400 is provided with an actuation structure 410 for the user to operate with their fingers and thus push the knob 400. In this embodiment, the knob 400 is disc-shaped, and the actuation structure 410 includes a retainer 411 erected on the knob 400. The retainer 411 is configured corresponding to the operation window 201; specifically, the retainer 411 can be configured inside the operation window 201 for the user to push and thus push the knob 400 with their fingers. In the simplest implementation, a single retainer 411 can achieve the intended operating effect; however, in this embodiment, at least one set of two retainers 411 is configured for each direction of rotation, and these two retainers 411 are vertically arranged. After placing their fingers between the two retaining walls 411 and pushing one of the retaining walls 411 to rotate the knob 400, the user can directly push the other retaining wall 411 in the opposite direction to reverse the knob 400. Moreover, in this embodiment, the actuation structure 410 includes two sets of retaining walls 411 to allow two fingers to drive the knob 400, making the rotation action less strenuous.
[0069] See Figure 3In the simplest embodiment, a single latch 300 and a single knob 400 are sufficient to achieve the intended linkage effect. In this embodiment, identical knobs 400 are respectively configured on the two opposite sides of the cabinet door 200, i.e., two identical knobs 400. Each knob 400 is linked to the latch 300 on its respective side.
[0070] Figure 5 This is a perspective view of the knob 400 in the unlocked position of the front-opening substrate loading box, which is compatible with the first embodiment of this application. Figure 6 Another perspective view of the knob 400 in the unlocked position of the front-opening baseboard loading box compatible with the first embodiment of this application. (See also...) Figures 5 to 6 Specifically, each knob 400 has at least one pin 402 for inserting into the corresponding latch 300, and when the knob 400 is rotated, the pin 402 moves about the pivot center of the knob 400 and can push the corresponding latch 300 to translate.
[0071] See Figure 1 and Figures 3 to 6 When the knob 400 is in the unlocked position, the knob 400 pushes the latch 300 into the box door 200 and releases the box 100, and the front-opening base plate loading box is in the unlocked state.

Figure 8 A cross-sectional view of the front-opening substrate loading box with its door 200 in the locked state, which is compatible with the first embodiment of this application. Figure 9 A perspective view of the knob 400 in the locked position of the front-opening substrate loading box compatible with the first embodiment of this application.
[0073] See Figure 1 and Figures 7 to 9 When the knob 400 is in the locked position, the knob 400 pushes the latch 300 out of the box door 200 and latches the box body 100, and the front-opening base plate loading box is in a locked state.
[0074] The handle 500 is disposed inside the door 200 and within the operating window 201; specifically, the handle 500 is disposed within the door seat 210. In this embodiment, a lock hole 401 is provided at the pivot center of the knob 400; specifically, the lock hole 401 is groove-shaped. In this embodiment, the handle 500 has a channel 501 corresponding to the lock hole 401. The handle 500 has a first handle portion 500a and a second handle portion 500b separately disposed, which are respectively disposed on two opposite sides of the operating window 201. The channel 501 is defined between the first handle portion 500a and the second handle portion 500b. However, this application is not limited to this; for example, the handle 500 may also be a single-piece component, with an opening at the position corresponding to the lock hole 401 to form the channel 501.
[0075] See Figure 7 and Figure 9 When the knob 400 is in the locked position, the keyhole 401 is aligned with the channel 501, allowing a key with a shape corresponding to the keyhole 401 to pass through the channel 501 and be inserted into the keyhole 401, thereby allowing the knob 400 to be rotated by the key.
[0076] See Figure 1 , Figure 3 and Figure 5 When the knob 400 is in the unlocked position, the user can grip the handle 500 with their fingers to easily remove the door 200 from the opening 101. When the knob 400 is in the unlocked position, the keyhole 401 is not aligned with the channel 501, causing the first handle portion 500a and the second handle portion 500b to partially obscure the keyhole 401. Therefore, the handle 500 prevents the key from passing through the channel 501 to insert or withdraw from the keyhole 401.
[0077] See Figure 3 In this embodiment, the knob 400 is provided with multiple baffles 411. Some of the baffles 411 can abut against the handle 500 in the unlocked position, thereby limiting the pivot stroke of the knob 400 and positioning the unlocked position of the knob 400. Specifically, as Figure 3 As shown, one of the retaining walls 411 abuts against the first handle 500a, and the other retaining wall 411 abuts against the second handle 500b.
[0078] See Figure 7 In this embodiment, another portion of the retaining wall 411 can abut against the handle 500 in the locked position, thereby limiting the pivoting stroke of the knob 400 and positioning the knob 400 in the locked position. Specifically, as Figure 7 As shown, one of the retaining walls 411 abuts against the first handle 500a, and the other retaining wall 411 abuts against the second handle 500b.
[0079] Figure 10An exploded perspective view of the handle 500 and knob 400 in the unlocked position of the front-opening substrate loading box compatible with the first embodiment of this application. Figure 11 A cross-sectional view of the handle 500 and knob 400 of the front-opening substrate loading box compatible with the first embodiment of this application in the unlocked position. Figure 12 This is a perspective view of the handle 500 and knob 400 in the unlocked position of a front-opening substrate loading box compatible with the first embodiment of this application. (See also...) Figures 10 to 12 In this embodiment, the handle 500 has a first barb 521, which hooks outward to the knob 400. This prevents the handle 500 from being subjected to excessive torque and bending, thus avoiding damage, when the user grips the handle 500 to remove the case door 200. Specifically, the knob 400 has a second barb 422, and the first barb 521 hooks into the second barb 422 to fix the handle 500 and the knob 400 together along the direction of removing the case door 200.
[0080] See Figure 12 To facilitate assembly, the handle 500 is provided with a first positioning wall 211 and a second positioning wall 212 within the door seat 210 corresponding to both the first handle portion 500a and the second handle portion 500b, and the end of the second positioning wall 212 has a hook 213. Taking the first handle portion 500a as an example, the bottom end of the first handle portion 500a is inserted between the first positioning wall 211 and the second positioning wall 212, and the hook 213 engages with the first handle portion 500a, thereby installing the first handle portion 500a to the door seat 210. Similarly, the second handle portion 500b is installed to the door seat 210 in the same way using another set of first positioning walls 211 and second positioning walls 212.
[0081] The front-opening substrate loading box of this application has an operating window 201 on its door 200 for a knob 400 used to actuate the latch 300. The user can access the knob 400 through the operating window 201 to rotate the knob 400, thereby driving the latch 300 to lock or unlock. A handle 500 is provided inside the operating window 201 for the user to grip and easily pick up the door 200. The knob 400 has a key hole 401, and the handle 500 has a channel 501 corresponding to the key hole 401, so the door 200 can be locked or unlocked by hand or key.
